UNITED STATES WILLIAM C. RASTETTER, OF FORT WAYNE, INDIANA.

FOLDING CHAIR.

Application filed May 20, 1924. Serial No. 714,582.

To all whom'it may concern:

Be it known that I, WILLIAM C. RAST'ET- TER, a citizen of the United Statesof Ameri-' ca, and resident of Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Folding Chairs, of which the following is a specification.

This invention relates to improvements in folding chairs, and. the object thereof is to provide a seat in connection with a folding supporting structure that will be held rigidl v when in position for use, and to provide also in pivotal relation with the seat folding braces having binding engagement with the folding supporting structure for sustaining the same when in position for use.

These objects are accomplished by the construction illustrated in the accompanying drawings, in which Fig. 1 is a side elevation of a folding chair embodying the invention, the main frame of therstructurebeing in central section;

Fig. 2 is a front elevation projected from Fig. 1;

Fig. 3 is a detail perspective view showing the connection between one of the braces and the corresponding arm of the prop; and

Fig. 4 is a fragmentary plan view showing one of the eyebolt connections thereon for the prop.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters. I

The invention comprises a main frame preferably formedof a strip 1 of wood bent in its middle to form a bow 2 with contiguous parallel legs 3, there being a cross-piece 4 and a bent bracket 5 connecting the legs at their lower ends.

Supported in the legs 3 is a horizontal r0 6 upon which is pivotally mounted a seat 7 and also in the frame is pivotally secured a U-shaped prop formed of a rod 8 shaped so as to have upwardly extending arms 9 the upper ends of which are respectively pivoted to the corresponding sides of the frame as indicated by 10.

The back end of theseat 7 has at each side thereof an eyebolt 11 through which the corresponding arm 9 of the prop extends, the eyebolts being slidable on the arms and limited in their upward movement b corresponding stops 12 fixed on the si e arms respectively. The shank 13 of each eyebolt extends through the corresponding projec tion 14 on the seat and is sufliciently loose as to admit of its turning axially therein.

made of leather or fabric, and the lower edge of the back is supported by a close coil spring 17 that is secured at its ends respectively to the corresponding arms 9. The spring yieldingly sustains the lower end of the back in connection with the prop. Upon the rod 6 between each leg 3 of the frame and the seat 7 is pivoted a brace 18 having fixed at its lower end a bracket 19 with a projecting wing 20 that has an elongated opening 21 therein through which the corresponding arm 9 of the prop extends.

In utilizing the invention the seat is turned upon the rod 6 in the main frame to horizontal position so that the eyebolts 11 bear upwardly against the stops 12 on the arms of the prop. The eyebolts hold the prop at a fixed angle relative to the main frame which thereby sustains the frame in proper position for use. When the prop is thus positioned, the braces 18 swing backwardly upon their pivotal support and the arms of the prop become bound in the apertured wings 20 due to the relative angularity of the arms and wings, the arms being sustained so that forward or backward bending of the arms is prevented, as may otherwise occur-especially when the chair is tilted back while sustaining the weight of the occupant. This is an important feature of the invention as it affords rigidity that is essential in light structures.

What I claim is 1. In a foldingchair, a main frame including a pair of legs spaced apart; a rod horizontally positioned with its ends secured to the corresponding legs; a seat pivotally supported on the rod; a prop member having arms, the upper ends of which are pivoted in the frame at points above the said rod; an eyebolt loosely mounted in connection with the seat at each side thereof back of said rod and having sliding movement on the corresponding arm of the prop member; a stop fixed on each arm operable to limit the upward movement of the corresponding eyebolt; a bracket pivoted on the rod between each leg and the seat; and a bracket on each of said braces having an angular wing with an elongated aperture therein through which the corresponding arm of the prop member extends, said brackets having binding'engagement with said arms when the seat is extended for use. i

' 2. In a folding chair, a frame having a pair of legs spaced apart; a rophaving arms, the upper ends of which ave pivotal connection in the frame; a seat having at its rear end limited sliding connection with the arms of the prop and extending between the legs of the frame; a pair of braces, one on each side of the seat and having sliding connection with the corresponding arms of the prop at points beneath the seat; and a horizontal rod mounted in the legs of the frame and affording common pivotal supportfor the seat and the braces, said braces having binding relation with the arms of the prop when the seat is in position for use.

3. In a folding chair having a supporting frame, a hinged prop in connection with the frame; a seat having hinged support in the frame at a point below the pivotal connection of, the prop and the frame, said seat having limited sliding movement on the prop; and

when-the seat is in position for use.

4. In a folding chair having a supporting frame and seat hinged therein, a prop in hinged connection with the frame at a point above the seat, said seat having limited sliding connection with the prop; and braces in pivotal relation with the seat having sliding movement on the prop below the seat and binding relation with said prop when the seat is in position for use.

In testimony whereof I aflix my signature in presence of two witnesses.
